(CNN) -- In the last "This Week in iReport" before 2010, we're having some holiday fun with multiple Santa sightings and over-the-top home decorations.

Santa sightings -- iReporters across the globe spotted not one, but several Kris Kringles congregating. From a Santa pub crawl in New York City to a chilly Santa Speedo race in Boston, Massachusetts, the photos and videos are priceless.

Extreme holiday decorations -- We asked iReporters to share their best home holiday decorations, and got a huge response. Christina Sosnowski sent photos of her parents' yard in Surprise, Arizona, which glows with 150,000 lights and dozens of illuminated characters. Not to be outdone, Bob Cox of Pittsburgh, Pennsylvania, spends months covering his home in a whopping 265,000 lights.
